And: I think if there's a RAM issue, it'd be with SIM 1, where there's still a little corrosion under - I think. Can the screen start without RAM in SIM 1? Can it start without any RAM? It may also be a ROM issue -the ROM looks like it had water spilled on it although I don't know that that did any real damage to the chips or circuit.

Is there really no barebones guide/tutorial for this? For instance... how would I know if the 68030 is fried?

And actually, are there any good guides to dishwashing? I'm probably close to that point. I've used a good deal of vinegar, rubbing alcohol, scrubbing bubbles and distilled water. There are still some problem spots.
